The Teledyne Electronic Technologies/Analytical Instruments (TET/AI)
Series 320BRC and 320P Portable Oxygen Detectors meet or exceed all of
the requirements of the Commonwealth of Europe (CE) for Radio Fre­quency Interference and Electromagnetic Interference (RFI/EMI) protec­tion. Models 320A and 320B are
the Commonwealth of Europe. The analyzers are designed to continuously
measure the percentage of oxygen in a gas atmosphere. The measurement
is specific for oxygen and no special standardization or zero gases are
required. A letter designation, after the model number, indicates a specific
version as specified by the customer at time of purchase.

complying with the requirements of

The 320A requires 115VAC or 220VAC 50/60Hz
The 320B uses four replaceable D-size batteries.
The 320BRC is powered by two permanently mounted recharge-

able nickel-cadmium batteries.
The 320P is powered by two permanently mounted rechargeable

nickel-cadmium batteries and has an integral sample pump. This
analyzer is designed to make spot check measurements of oxygen
in flue gas and process gas streams.

Oxygen is sensed using a TET/AI patented micro-fuel cell (MFC), that
consumes oxygen from the atmosphere surrounding the measuring probe
and generates a proportional electric current. The generated current is
amplified and read out on a built-in meter. A voltage output is available for
driving an external recorder. A selective range attenuation circuit and a
temperature compensation circuit provide temperature compensated out­puts.

The standard operating ranges for Models 320A, 320B and BRC are 0-5%,
0-25% and 0-100% oxygen. The standard operating ranges for the Model
320P are 0-5%, 0-10% and 0-25% oxygen.

The 320 series detectors sample by diffusion in three different modes.

The MFC carries a warranty that covers its normal life expectancy. How­ever, far greater life expectancy can be achieved with the cell-saver feature.
The cell-saver is a sealing cap that keeps oxygen from the cell when the
instrument is not in use. With the cell-saver cap in place, the output drops
to less than 10% overnight and continues to drop as long as the cell-saver
cap remains in place.

• The probe assembly is mounted in the probe holder on the side of
the unit. The sample flows over the probe, using the accessory
flow-through adapter (P/N A9689).

• This is done remotely by removing the probe assembly from its
holder and extending the coiled probe cable up to six feet.

• An accessory probe mounting bar (P/N A8657) which is part of the
optional probe (P/N B16952) can be used to mount the probe in a
fixed position (remote location) if the application warrants at the
time of ordering the unit.

• In the case of Model 320P, the analyzer's integral pump draws the
sample through the analyzer. If the sample is at a positive pressure,
it is not necessary to operate the pump.

not necessary to operate pump.

A sealing cap is provided to keep oxygen from the cell when the instrument
is not in use. With the cell-saver cap in place, the cell slowly consumes the
trapped oxygen, and the output drops off towards zero. Overnight the
output will drop to less than 10% and will continue to drop as long as the
cell-saver cap remains in place.

The equilibrium oxygen level depends upon the integrity of the seals in the
probe assembly. The better the seals, the closer to zero the output will
drop. (The seals were designed to achieve an equilibrium of 2% or less.)

The MFC carries a warranty that covers its normal life expectancy. How­ever, far greater life expectancy can be achieved with the cell-saver feature
already discussed. See the specifications section below for warranty,
response time and electrical output of the various cells.

Customers having warranty claims must return the cell in question immedi­ately to the factory for evaluation. If it is determined that failure is due to
faulty workmanship or parts, the cell will be replaced at no cost to the
customer. Any evidence of tampering, or damage through mishandling, will
render the cell warranty null and void.

If a cell was working satisfactorily, but ceases to function before the war­ranty period expires, the customer will receive credit, on a prorated basis,
towards the purchase of a new cell.

The cell is furnished in a controlled atmosphere package that extends its
useful life by a factor of 20. A spare cell can be stored without appreciably
shortening its useful life as long as the seal on the package is not broken.

NOTE: Orders for replacement cells must include the cell class. Refer

to the Specifications section below.

To install the new cell:

1. Remove probe assembly from the probe holder.

2. Unscrew the cap from the top of the probe assembly.

3. Place the cell in the probe with the terminal end of the cell facing
down towards the probe contacts.

4. Replace the probe cap.

NOTE: Be sure that the probe cap is tightened all the way down and

that the probe body is sealing on the gasket of the probe cap.

With samples that contain CO2, such as flue gas, the maximum sampling
time for any one sample taken is 5 minutes.

CAUTION Ensure that the sampling time is as short as possible. One

minute per sample is normally more than adequate.
Frequent sample exposure for more than five minutes will
shorten cell life.

After each sample exposure, set the range switch to the 0-25 % position.
(This is the HI position on the standard 320P.) Then purge the instrument
with air using the built-in pump.

In applications where intermittent samples are taken in one location, expose
the cell to air (20.9 % oxygen) until a constant reading is obtained. Then the
flow-through adapter can be removed.

Leave flow-through adapter off until next measurement is required. This is
done in lieu of purging the instrument with air. However, after final mea­surements are taken, purge the instrument with air before replacing the
flow-through adapter.

Abnormally slow recovery to the air calibration point (5-30 minutes) is
characteristic of cells operated in CO2 containing atmospheres for periods of
longer than five minutes.
